HORN OR BELL ATTACHMENT.

Specification of Letters Patent.

Patentedsept. 1o, 191s.

Application led October 18, 1917. Serial N o. 197,319,

ably mounted upon a horn or bell for harmonizing the secondary tones thereof although .increasing the volume of the device.

jAnother object of this invention is the production of a horn or bell attachment which consists of a casing supported upon the horn or bell to receive and project a secondary soundV of the horn or bell thereby harmonizing although increasing the volume of the tone of the horn or bell upon which the structure is carried.

Another object of this invention is the production of a horn or bell wherein the casing is substantially cylindrical and is provided with a head at one end thus allowing the attachment' to be positioned upon a horn or bell, although the flared end portion of the attachment will ermit the sound waves to be projected there rom, thus harmonizing l the tones and sound waves of a horn or bell upon which the same is carried, although increasinfr the volume of these waves.

A still further object of this invention is the production of a washer which is mounted upon the horn or bell and fixedly bears upon the casing for holding the same against accidental movement after being positioned' upon the horn or bell. With these and other objects in view, this invention consists of such novel combinations, constructions, and arrangement of parts and will hereinafter be fully described and claimed. Several practical forms of embodimentof the present invention are shown and described, in the accompanying drawings, in whichn o Figure 1 is a 4central longitudinal section through the horn or bell attachment showing the same mounted upon a horn.

Fig. 2 is a longitudinal section through the attachment` illustrating the same mounted f upon a bell,

F ig..3 is a longitudinal section through the inventlon mounted'upon a horn, and

Fig. 4 is al transverse sectional view through the device shown in Fig. 3.

Referringto the accompanying drawingy by numerals, and particularly to Fig. l', it will be seen that the attachment is 'mounted upon a horn which comprises the usual conical'body 1' having a bell 2 thereon. L

The attachment comprises a cylindrical casing 3 having a closed head 4 at its inner end.v This head 4 is provided with a central opening 5 vsurrounded by the conical sleeve 6. The opposite end of the casing 3 is provided with a bell 7. The horn'body 1 is 'i passed through the casing 3 and proj e'cts'b'e-4 yond the sleeve 6. Owing to the fact that this sleeve 6 is conical in form, as shown in Fig. l, it .will bind upon the horn body l for fiXedly retaining the casing inA an adjusted setposition. At this timethe-bell `7 of the casing 3 will be spaced from .the bell 2 of the horn body 1. As a result, the secondary tones and sound waves vibrating from the horn body 1 and the bellv 2 will be received and modified within the casing 3 to be harmonized, although the closed construction of the inner end of the attachment lwill cause these sound waves to be projected therefrom in an increased volume, passing elements 14 of the bell 8 project. For this i reason a head 12 will bearupon the'4 upper end of the bell 8 and cause the attachment to be supported so that the bell or flared portion 11 of the casing l0 will be spaced 'fromf the enlarged portion 9 of 'the bell 8. lThe secondary tones and sound waves vibrating and proceeding from the bell 8 will be received in the casing wherein they will be harmonized and then projected in an increased volume from the outer end of the casing, by passing between the enlarged portion 9 of the bell-"8 and the bell or flared portion l1 of the casing 10.

Byzreferring to Figs. 3 and 4, itwill be 2 argv seen that the bell 8 is provided with an enlarged lower end i), as is the usual construction of bells. The casing 10 is provided with a bell or flared portion 11, While the head 12 is Jformed intcg 1al upon the 'casing 10. rlhis head 12 is provided with a central opening ldthrough which the retaining lugs or elements 14 of the bell 8 project. For this reason a head 12 will bear upon the upper end of the bell 8 and cause the attachment to be supported so that the bell or flared portion 11 of the casing 10 Will be spaced romthe enlarged portion 9 of the bell 8. The secondary tones and sound Waves. vibrating and proceeding from the bell 8 xv`ill`be received in the casing wherein they Will be harmonized and then,projectedinan increased volume from the outer end of the casing, by passing between the enlarged portion 9 of the bell 8, and the bell .or iiared portion 11 of the casing 10.

By referring to Figs. 3 and 4, it Will be seen that the conical formed body 18, is provided With the usual bell portion 2. The cylindrical casing 16 is provided with a bell portion 17 adjacent one end While a head 415 is formed upon the opposite end of the casing 16. This head 15 is provided With a central opening 15 surrounded by the conical sleeve 18, whereby the horn body 1 may b'e passed through the opening 15 and may engage the conical sleeve 18 for assisting in retaining1 the casing in an adyjustedset position upon the horn.

It 'maypbe desired, or necessary, to prov'idcanidditional retaining means for holding the attachment against displacement and for this reason the Waslihr 19 having a central ope'ning 20 is positioned upon the horn body .1', as illustrated in both of the last mentioned figures.I This Washer 19 is provided with a plurality of sound perforations 21 formed therethrough, as shown' clearly in Fig. 4, for allowing the sound Waves to pass through the opening and be projected from the attachment When the sam/e is in use. This washer 19 is positioned upon the horn body 1 and-then. the attachment is positioned as indicated in Fig. 3. As the attachment is wedged onto the Washer '19, and owing to the conical `construction of the horn body -1 it is obvious that the casing will be positively held against accidental displacement. AThe sound Waves caused by the vibration of the horn Will be received within the casing and to the closed end of the inner endv of the casing, Will proceed through the openings *or perfor-ations 21 formed in the Washer 19 to be `inally projected between the bell 17 of the attachment and the bell 2 Vof the horn. i

It is ot course obvious that the attachmentV herein shown may be connected to horns and bells of motor vehicles, or may be of such size as to be lmounted unen the horns ot` orchestra and band instruments, as well as to horns and bells ot any and general construction. lt should of course be understoml that the attachment may be made ot anyY desired length., such for instance as will s viufhronize the l'nllsations of air Within the casing with the vibration of the flaring bell. ldlnthermore, should the device be used` as suggested in Fig.- 3, for instrlunents ot' orchestra and band nature, the length ot the casing must correspond t0 the pitch ot' the horn, being shorter for high pitched tones, as sound Wave lengths are shorter in high tonos although longer in low tones and tor this reason the attachment must be of the proper length necessary to produce the volume and tone desired.

1t is obvious that many minor detail changes may be made in the construction of the present invention, say for instance as the length and shape of the device, Without departing from the spirit ofthe invention and for this reason it is not intended to limit the construction of this horn or bell4 attachment to the Yspecific Jforms herein shown, as it is intended to include all such forms of the invention as properly comes withi n the scope of the invention as claimed.
